Metaspeed Sky Paris vs Endorphin Elite 2

The Metaspeed Sky Paris is ASICS at full race trim: a carbon racing shoe built for one job, chasing a personal best on the road. It is the cadence runner's racer, the half of the Metaspeed line tuned for runners who get faster by keeping their stride length and turning their legs over quicker, while the Metaspeed Edge Tokyo handles those who lengthen their stride. At 215g with a full-length carbon plate and a 5mm drop, it is light, aggressive and unmistakably a marathon shoe rather than a do-everything trainer. The bouncy, springy foam and stiff plate work together to roll you forward and reward a committed effort. Hold goal pace and it comes alive. Jog it easy and you will wonder what the fuss is about. In our view it sits right at the top of the carbon racing shoe pack alongside the Nike Vaporfly 4, and at £260 it is priced like the elite tool it is.

Saucony swapped the firm foam of the first Elite for something far softer, and the Endorphin Elite 2 ended up as one of the bounciest carbon racing shoes around. Lab testing at RunRepeat rated its midsole the softest they had measured, and reviewers mostly describe a ride that squashes at easy pace and pushes back once you speed up. That makes it a marathon shoe before anything else, and it's also why it wobbles. The Run Testers found it unsettled on fast corners and slippy in the wet, and pointed to the Metaspeed Sky Paris as the steadier pick. The toe box is narrow as well. With steady mechanics and slim feet, you get a very lively half or full marathon shoe. If your form tends to fade late in a race, the Endorphin Pro 4 is calmer and cheaper, and Saucony has since followed it with the Endorphin Elite 3.
